Just like Wikipedia, you can contribute new information or corrections to the catalog. You can browse by subject, author or lists members have created. If you love books, why not help build a library?
PicLits.com is a creative writing site that matches beautiful images with carefully selected keywords in order to inspire you. The object is to put the right words in the right place and the right order to capture the essence, story, and meaning of the picture.
Folding Story is a writing game where each writer is constrained to write one line of a story (120 words or less) and pass it on to another writer to add to it. Each user gets just three minutes to write a line. You get to be on the scoring leaderboard by the number of likes you receive for your lines. In the end, everyone can read the finished story. You get to read some pretty wacky stories because each writer gets to read just the last line entered. It's a neat writing exercise because the time and word limit really gives creativity an adrenalin shot.
